Sample storage class and volume for HCL Digital Experience 9.5 containers

Learn how to set storage class and volume using a sample storage class and volume scripts for HCL Digital Experience 9.5 CF171 and higher container releases deployed to Amazon Elastic Container Service (EKS) or Red Hat OpenShift environment.

It is recommended to set a separate storage class and volume for production, especially if you have more than one project in the Kubernetes (Amazon EKS or Red Hat OpenShift) environment. This is a good practice because it prevents projects from overlapping storage volumes.

Follow these steps to create a new persistent volume and storage class, in either Amazon EKS or OpenShift.

Use and save the following as your storage class file:

kind: StorageClass 
                    apiVersion: storage.k8s.io/v1 
                    metadata: 
                    name: dx-deploy-stg 
                    provisioner: kubernetes.io/no-provisioner 
                    reclaimPolicy: Retain 
                    volumeBindingMode: WaitForFirstConsumer

Use and save the following as your storage volume file:

kind: PersistentVolume 
                    apiVersion: v1 
                    metadata: 
                    name: wp-profile-volume 
                    spec: 
                    capacity: 
                    storage: 100Gi    
                    nfs: 
                    server: your_nfs_server.com 
                    path: /exports/volume_name 
                    accessModes: 
                    - ReadWriteMany 
                    persistentVolumeReclaimPolicy: Retain 
                    storageClassName: dx-deploy-stg 
                    mountOptions: 
                    - hard 
                    - nfsvers=4.1 
                    - rsize=8388608 
                    - wsize=8388608 
                    - timeo=600 
                    - retrans=2 
                    - noresvport 
                    volumeMode: Filesystem

Copy both files to your local file system.
Change at least the server and path in your sample volume .yaml file to an appropriate NFS server and volume.
To create the storage class, run the following command:
```
kubectl apply -f subclass.yaml
```
To create the storage volume, run the following command:
```
kubectl apply -f SampleZVolume.yaml
```
Continue with deployment.

Note: In these examples, NFS volumes have been used. You can use the following sample yaml to create the volume in Amazon EKS OpenShift with the corrected values:

nfs:     
                server: your_nfs_server.com     
                path: /exports/volume_name
